Murano Style Art Glass Ribbon Swirl Plate

This is a circular art glass plate or shallow dish characterized by a distinctive 'ribbon swirl' or pinwheel motif. The piece is constructed from thick, heavy clear glass and features internal ribbons of vibrant green pigment that spiral outward from the center. The exterior rim is sculpted with rounded, scalloped indentations that align with the internal glass channels, creating a tactile and reflective textured edge. The center of the plate includes a flattened, square-shaped base which likely facilitates stability when placed on a surface. This style of glasswork is highly reminiscent of mid-20th-century Venetian or Murano craftsmanship, specifically the 'A Canne' or 'Zanfirico' techniques where colored rods are fused into clear glass. The glass appears to be in fair to good condition, showing some surface dust and minor scuffing consistent with vintage household use and shelf storage. There are no immediate visible large chips or cracks, although the edge should be checked for micro-flea bites. A small white rectangular adhesive residue or tag is visible on the central interior, which could obscure a maker's mark or simply indicate a previous price tag. The overall quality suggests a mass-market art glass piece from the 1960s to 1980s, designed for decorative use as an ashtray or candy dish.
